Elemental Influence on Dielectric Properties and Loss Tangent in CaCu₃Ti₄O₁₂ Ceramics

In this research, we explore novel doping and co-doping strategies to enhance the performance of calcium copper titanate (CaCu₃Ti₄O₁₂, CCTO). The focus is on incorporating different elements like bromine and fluorine these elements are doped alone and as well as together we have seen a huge difference in it as compared to pure calcium carbon titanate, these elements changed the CCTO structure and to investigate their effects on the material's properties. The chemical formulas of the doped and co-doped compounds are CaCu₃Ti₄(O,Br)₁₂, CaCu₃Ti₄O₁₂₋F₂ₓ, and CaCu₃Ti₄O₁₂. Detailed analyses of structural and dielectric properties were performed to understand the impact of these dopants. Our findings demonstrate significant improvements in the dielectric constant and overall stability of the material, which hold promise for advanced applications in electronic devices.
